COTTON-SEED DELINTER.

SPECIFICATION forming part of Letters Patent No. 597,123, dated January 1 1, 1898.

Application filed June 3, 1895. Serial No. 551A80. (No modeLl T0 aZZ whom it may concern:

Be it known that I, J OHN S. ROSAMOND, a citizen of the United States, residing at Memphis, county of Shelby, and State of Tennessee, have invented certain new and useful Improvements in Cotton-Seed Delinters, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to that class of machinery known as cotton-seed delinters, the purpose of which is to separate or recover from the surface of the cotton-seed all the short cotton fibers or lint adhering thereto and not detached by the ginning operation, the object being not only to clean the seed, but to recoverthe useful lint therefrom.

The object of the invention is the production of a machine whereby the short cotton fibers orlint will not only be thoroughly and perfectly removed from the surface of the cotton-seed and recovered without injury thereto, but the operation be performed at a high rate of speed upon a large quantity of cottonseed in a given time.

The invention consists in an improved construction of the delinting-cylinder in respect of its abrading or scouring devices and its stirring devices.

The invention embraces improved seed feeding, conveying, and retarding devices. It also includes insulating the delinting devices, and embodies various combinations of devices, all of which features of invention are so fully hereinafter set forth and claimed as to require no more specific preliminary explanation.

A practical embodiment of these improvements is illustrated in the accompanying drawings, in which- Figure 1 is a plan view of a machine embodyin g my invention,portions being removed to expose inner parts. Fig. 2 is a longitudinal central sectional elevation of the same. Fig. 3 is a transverse sectional elevation of the same, taken on a central line of the main cylinder of the machine. Fig. 4 is an elevation of the receiving end of the debuting-cylinder, showing its carrying-wings; and Fig. 5 is a perspective view of one of the delinting-blocks.

In order to readily understand this invention, the general structure of a machine embodying it will first be given. The delintingcylinder consists of a core or body A, mounted upon a shaft, so as to revolve in bearings provided in a suitable framework, as 100, which cylinder is inclosed within a casing B, that is provided through its top at one end with a feeding-orifice 20 for the seed to be treated and at the opposite end of its top with a discharging-orifice 21 for the denuded seed, At its bottom this casing is provided with a screen or grating 22, which While allowing dirt and impurities to be discharged therefrom at the same time causes the seed and the fibers to be retained therein.

The core or body A of the delinting-cylinder is constructed preferably of wood having metallic protecting ends 23 24; but obviously it may be formed from metal, in which case it will be a hollow structure. This core or bodyA is clothed throughout the major portion of its exterior surface with securing or abrading blocks 2, cast out of emery, or, as

an equivalent thereof, a similar grinding or abrading material, which blocks are hereinafter referred to for brevity as emery blocks. These emery blocks 2 may be madev in many shapes and still embody the improvements set forth herein. In one preferable form they are elongated and have longitudinally arched or curved seats or bottom surfaces to adapt them to fit snugly upon the surface of the cylinder-body and are transversely arched or have curved sides and top, and they are provided with tapered or wedge-like forward ends, preferably embodied in a rounded or conical formation, as shown in Figs. 1 and 5, and in another preferable form their bottom portions are provided with flanges 26, which project laterally to an extent equal to the furnishing of ameans for receiving screws 6 or similar means of attachment, whereby they are secured to the core or body A, and said blocks are separated and maintained a distance apart. These emery blocks are arranged circumferentially upon said cylinder and preferably in concentric rows, the blocks in alternate rows breaking joints or being staggered, as is well illustrated in Fig. 1, by which arrangement the emery blocks will be separatedsidewise by longitudinal channels 7 and endwise by transverse channels 8, (see Fig. 1,) so that the course of travel of the seed undergoing treatment will be in part a movement through the longitudinal and lateral channels, in part upward over the rounded tapered or wedge-like forward ends of the emery blocks, and in part laterally over the transversely curved or rounded bodies of the emery blocks, and in order that the mass of seed and lint may not become so compacted or tangled as to obstruct its movement, and thus prevent its subjection to the abrading treatment of the surfaces of the emery blocks, stirring-pins 3 are interspersed throughout the mass of emery blocks so isolated from each other as to properly act in breaking up this tendency to knot and obstruct the delinting action.

It will be observed that each row of blocks 2 is provided with at least one stirring-pin 3, the whole thus forming a spiral series of pins, said pins being separated from each other by at least two blocks and by two rows of blocks, which spiral arrangement provides a. pin which sweeps circumferentially in the line of division between every two rows of pins, whereby any clogging in that circumferential plane is broken up, and the series sweep longitudinally with a progressive action that aids in moving the mass toward the deliverypoint. This arrangement is a practical one, whereby the delinting operation is accomplished without injury to the seed, while stirring-pins set too closely together results in tearing and destroying the seed.

At the receiving end of the machine the delinting-cylinder is provided with a conveyor consisting of a series of wings 4, fixed to the cylinder-body at such an angle with respect to the axis thereof as is required by the speedat which it is desired to propel the seed undergoing treatment through the machine.

The casing B, within which the delintingcylinder rotates and through which the machine is fed and the products discharged, may be of iron with or without an interrupted or undulating surface, but preferably is constructed of wood in such a manner as to impart to it great strength to resist the interior pressure exerted by the action of the mechanisms, said wooden casing being clothed interiorly with a lining 70, composed of emery or similar abrading or scouring material attached thereto in segmental sections or otherwise, and at one side this casing is provided with a grated section composed of curved bars 5, between which a gang of saws operate, the function of which saws is to remove from the machine by their clawing action such fibers as are carried across or between said bars, and in order that the fibers detached from the seed may take that course the said gang of saws is inclosed within a trunk 30, with which is connected a blower, as E,which tends to produce a vacuum in the interior of the trunk 30, that draws the loose fibers against or into said grating and within the range of action of the said saws. This blower E is of ordinary construction, composed of wings 40, mounted upon an axis and made to revolve in a circular casing. It is vented at 13 by an orifice perforating the bottom member of the trunk 30 throughout its width near the saws 10. The air-current is drawn through the vent 13, (the space between the delinting-cylinder and its casing being kept filled with seed, and thus opposing the passage of air through the grating 22,) and this current, passing outward toward the blower E, meets its angular guard 25 in the trunk 30 and is deflected thereby to each side of the blower E, entering Within the blower by the openings 27 in its opposite sides and being discharged through the chute 41. In order to detach these fibers from the rotating saws, there is provided an ordinary revolving cleaning or detaching brush 31, which, rapidly revolving,

whips the fibers out of the teeth of the saws,

and thus liberates them to be carried outward by the drawing action of the air-current produced by the fans or blades 40 of the blower E, whereby the detached fibers or lint are de livered through the chute 41 for further treatment, which trunk may lead to a condenser or to a mere storage-bin, as may be desired.

The feeding-orifice 20 is provided with a feeding-conduit 92, that communicates with a carrying-trough 90, in which revolves a pro- .peller9l,thatis supplied from a chute 99 with the seed to be treated. The deliveryorifice 21 is provided with a discharge-conduit 93, which has a discharging-opening 97 controlled bya sliding gate 95, that communicates with a delivery-chute 96, which will convey the seed to abin or otherwise, as may be desired. Within this conduit 93 there is provided a sliding plug 94, which maybe adjusted to a given height in said conduit by means of its adjusting-pin 89, which enters a suitable one of a series of holes 12 in the side of said plug 94. This plug acts as a regulator of the pressure exerted upon the body of seed within the machine, the delivery of which is through the orifice 21 and into the conduit 93 and thence out of the opening 97, said pressure being greater or less according as the plug 94 is lowered or raised.

The delinting-cylinder, the gang of saws, the revolving brush, the blower, and the feeding-screw are each shown as provided with driving-pulleys, whereby they maybe rotated at suitable speeds. No gearing is shown, but the direction of movement of each of these devices is indicated by arrows associated with them, and this gearing may be of any suitable kind, the speed of each device being regulated according to experience.

The operation of the machine is as follows: The seed in the condition in which it is received from the cotton gin is delivered through a chute 99 from its bulk to the propeller 91, which feeds it onward in the trough 90 toward the feed-conduit 92, down which it is moved by the force of its own gravity and the pressing action of said propeller. Un-

der this pressure the seed entering the machine at the receving end of the delintingcylinder A is borne upon by the conveyingwings 4, the inclined arrangement of which with relation to the axis of the cylinder carries the seed onward in aspiral direction until the cylinder or casing B is completely filled from one end to the other, the seed then bein g driven or pressed upward out through the delivery-orifice 21 and into the delivery-conduit 93, thence outward therefrom through the discharge-opening 97 into the chute 96, its movement or passage being resisted by a pressure regulated according to the lowered or raised position of the plug 94, by the use of which as a pressure-regulator results a perfect control of the movement of the seed undergoing the delintin g or cleaning operation, and hence the duration of time in which the transit of the seed is made through the machine, and therefore the degree to which it is subjected to the abrading or scouring action, and consequently the perfection or completeness by which the surface of the seed is cleansed of the adhering lint or cotton fiber. When this pressure is so great as to overcome the force with which the propeller 91 acts to deliver seed to the conduit 9:2, the surplus quantity of seed will be carried past the conduit 92 and overflow out of the conduit 88 or pass therefrom to feed another delinting-machine. As the abradingbylinder revolves the body of lint-coated seed pressed into and made to travel within the space between the outer casing and the delinting-cylinder will be plowed into and lifted by the rounded, tapered, or wedge-like heads or forward ends of the emery blocks and turned and tumbled by their transversely-curved bodies and thus be forced or rolled into rubbing contact with the abrading-surfaces of both the blocks and casing,which detach or separate the lint therefrom. The detached fibers will, under the centrifugal action of said cylinder and the influence of the vacuum produced in the trunk 30 by the fan 40, be carried against or into the grating 5 and be stripped therefrom by the teeth of the revolving saws 10, which will carry the fibers outward until they meet the revolving brushes 31, whereupon the latter will act to detach the fibers and throw them outward in the trunk inclosing the saws and brush and leading to the blower, from which trunk the fibers will pass outward through the chute 41 and be delivered for use.

By the operation of this machine it is to be noted that the cotton-seed undergoing the operation of separating the lint adhering to its surface is carried through the cylinder under a pressure, which pressure is controllable, so that the time of the transit of the seed through the machine may be determined and hence the abrading action thereon be controlled, the result of which is that the cotton-seed may be most perfectly rid. of its coating of lint and the best condition of the seed for useful purposes be arrived at and the greatest recovery of lint be accomplished.

It is to be observed that the isolated arrangement of the stirring-pins interspersed among the emery blocks is important, as the tumbling or stirring action produced by these pins is proportioned to the movement longitudinally in the machine of the material undergoing treatment, this arrangement being such that the material operated upon is prevented from knotting up and clogging the machine and at the same time is not stirred or threshed to such an extent as to injure the seed which would result from a compact arrangement of such stirringpins.
